Let R he a commutative Noetherian ring, \fraka an ideal of
R and M a finitely generated R-module. Let t be a
non-negative integer such that Hi\fraka(M) is
\fraka-cofinite for all i < t. It is well-known that
HomR(R/\fraka, Ht\fraka(M)) is finitely generated
R-module. In this paper we study the finiteness of
Ext1R(R/\fraka, Ht\fraka(M)) and
Ext2R(R/\fraka, Ht\fraka(M))
